| 0 | PI 641165 | CJ 9306 | Triticum aestivum L. subsp. aestivum | Jiangsu Sheng, China | NSGC |  | | 2005 | DEVELOPED | 2001 | | | | | Breeding material | Awned, semi-dwarf and red-grained spring type with red glumes. Has a high level of resistance to Fusarium head blight (FHB or scab) caused by Fusarium graminearum. Scores for disease severity (such as number of scabby spikelets) under single-floret inoculation were consistently lower than the resistant check Sumai 3 or Ning 7840. Under a natural epidemic of scab, CJ 9306 scores for disease index were near Sumai 3 scores. Is superior to Sumai 3 in the resistance to disease spread of wheat scab, and is similar to Sumai 3 in comprehensive resistance. Under field conditions at Nanjing, China, its plant height was around 90 cm (30 cm shorter than Sumai 3). The spike length, spikelets and kernels per spike were around 11 cm, 22 and 38-40, respectively (10 cm, 21 and 34-36 for Sumai 3). Grains are red. oval, semi-soft and plump. 1000 kernel and test weights were 34 g and 756 g/l, better than those of Sumai 3 (33 g and 750 g/l). Biomass per stalk, grain yield/spike and harvest index were 3.5 g, 1.4 g and 39.7%, compared to Sumai 3 (3.2 g, 1.1 g and 35.1%). Duration of growth is around 210 days in Nanjing, and 100-110 days in greenhouse. Had earlier maturity (1-2 d) and stronger lodging resistance than Sumai 3. Moderate to rusts and powdery mildew. | 1686109 | PI 641165 |
